Hello Richard Bariny,
Welcome to the Microsoft Q&A Community!
The LiveKernelEvent 1b8 is logged by Windows’ internal kernel watchdog (WATCHDOG4400) when a hardware driver or device fails to respond within a critical time window. While it may not trigger a full blue-screen crash, it typically indicates a runtime fault—often related to GPU drivers or unstable hardware behavior.
🔧1: Check for Dump Files
To investigate further, follow this guide to locate and analyze any available dump files: 🔗 Read Small Memory Dump Files – Microsoft Learn
If you find relevant .dmp files, feel free to upload them to a personal cloud drive and share a link here for review.
🎮 2: Reinstall GPU Drivers Using DDU
Most LiveKernelEvent 1b8 errors stem from GPU driver instability. To fully clean and reinstall:
- Download Display Driver Uninstaller (DDU)
- Boot into Safe Mode
- Run DDU to remove all traces of your current AMD or NVIDIA driver
- Reboot and install the latest WHQL-certified driver from the manufacturer’s website
- Or roll back to a previously stable version if issues persist
For NVIDIA users: During installation, choose Custom > Clean Install to reset registry keys and ensure full compatibility
